      All Appliantology tech members are invited to join in this workshop on all things Appliantological. 
      We have a special session planned for this one. Instead of the usual Show 'n Tell on a technical topic, we're going to post tech sheets in the comments to this Calendar Event (scroll down to see what's posted so far) and ask specific questions that can only be answered by reading the tech sheet. If you at least try to answer the questions beforehand, you'll get a lot more out of it. The tech sheet and the questions are posted in the comments section below.
      Your mission, if you should choose to accept it, is to check out the questions for each one and try to answer them ahead of time. Then come to the Dojo to see how well you did! 
      Who: This workshop is only available to tech members at Appliantology.
      When: Saturday, April 27 @10:00 AM Eastern Time.
      Where: Online via Zoom
      How:

Linear compressor issues

Recommended Posts

I have a LG LFX25976ST/00 and the new compressor (with new inverter board) ran for about 15 min or so just fine. Then the led light on the inverter board started flashing 3 times. At this point the suction pressure went up to about 20-30 PSI. I reset the unit. (unplugged till light cleared) and it would run without a blinking light but with the higher suction pressure. When i pushed the button to but it into test mode it would pull down for a couple minutes and then start blinking 3 times on the inverter board. I have the service manual but it only shows what codes are for 2,4,5,6,7 blinks. And yes I have made sure it is 3 times not 6. When it is in test mode the voltage to the compressor ramps up to about 300. when it is running but the suction pressure is high, the voltage is in the low 200's. It is the TCA36411701 compressor with the ABQ73004304 inverter board. 

I am very confused about what is going on. Any suggestion would be appreciated.

Last one I worked on like this with a three blink was a connect error code I believe, check capacitor harness
